I've been very busy the last few weeks so I didn't have much time for this project, but the good news is that I can focus on this project completely from now on.

Thanks for the reactions and name-suggestions. The projectname will be Custom Fields Manager.

My milestones are:

• Create contenttype manager
• Create fields manager
• Create article manager
• Create template manager
• Create frontend article-display

I'm currently still working on the contenttype manager.

I've looked at existing solutions (like Drupal CCK) and I like the functionality that you can add your own field-types (selectlist, radiobuttons etc.). So I am going to implement that in the fields manager.
